Benedict Cumberbatch and Keira Knightley also star in director Morten Tyldum's film about the English code-breaker and early computer scientist Alan Turing.

Charles Dance (Gosford Park), Allen Leech (In Fear, TV’s Downton Abbey) and Matthew Beard (An Education) will also turn out for the movie, directed by Norwegian filmmaker Morten Tyldum (Headhunters) from a screenplay by Graham Moore, based on the book Alan Turing: The Enigma by Andrew Hodges.

Turing (Cumberbatch) was a U.K. mathematician and cryptographer who helped crack the German enigma code during the final years of World War II, helping the Allies to victory. He was later prosecuted by the government for being a homosexual and committed suicide.
